I don't disagree with you that learning to feel inner peace in yourself (the true purpose of the "abundance mindset", which is to help YOU as an individual feel OK with your life as it is right now) is not sufficient to change the world as a whole for the better.

But you are allowed to be happy and find inner peace with the imperfect world as it is, while at the same time helping others. It's not a zero sum game.
